Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority based on a Chinese patent application with application number 202110990780.9 filed on August 26, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the technical field of electronic atomizers, and more particularly to an electronic atomizer and its heating assembly. [Background technology]

[0003] Currently, electronic atomizers are heating and non-combustion devices, and the heating assembly in the electronic atomizer mostly heats the substrate to be atomized by central heating and peripheral heating. Because the thermal conductivity and thermal diffusion coefficient of the heating element are small, only a small part of the heat generated by the heating element is used to heat the substrate to be atomized, and the aerosol content generated is low. On the other hand, most of the heat is transferred to the entire electronic atomizer device through solid members in contact with the heating element, and each member and the housing of the electronic atomizer are heated. In order to increase the aerosol content, it is necessary to increase the heat output of the heating element, but this will cause more problems. For example, electronic atomizers consume large power, have high temperatures of the entire device and the housing, have short continuous operation times, and have long pre-heating times, and at the same time, the temperature of the electronic atomizer rises, which poses a great risk to the reliability of electrical components such as cells and circuit boards.

[0035] The casing 1 has an installation space 11, and an opening (not shown) is provided in the casing 1 to communicate the installation space 11 with the outside of the casing 1 through the opening. The heat generating assembly 2 is accommodated in the installation space 11, and the installation position of the heat generating assembly 2 is installed corresponding to the opening in the casing 1, so that the heat generating assembly 2 is exposed or communicates with the outside through the opening. The heat generating assembly 2 is fixedly connected to the casing 1 or detachably connected.

Fig. 4 is a schematic diagram of a specific embodiment of a fixing member in a heat generating assembly according to the present invention. Fig. 5 is a schematic diagram of a specific embodiment of a sleeve in a heat generating assembly according to the present invention. Fig. 6 is a schematic diagram of a specific embodiment of a heat generating member in a heat generating assembly according to the present invention. Fig. 7 is a schematic diagram of a specific embodiment of an elastic member in a heat generating assembly according to the present invention.

[0037] The heat generating assembly 2 includes a fixed member 21 , a movable member 22 , a heat generating member 23 , an electromagnetic generating member 24 and an elastic member 25 .

[0038] 4, the fixed member 21 has a barrel-shaped structure, has a mounting cavity 211, and is provided with a window 215, which communicates with the outside of the fixed member 21 through the window 215 so as to facilitate insertion of the aerosol generating assembly 4 into the mounting cavity 211. In addition, the fixed member 21 has a window 215 at its end fixedly connected to the top wall of the casing 1, and the window 215 is disposed in correspondence with and communicates with an opening in the casing 1.

[0039] In one embodiment, the fixed member 21 specifically includes a second annular side wall 212 and a second bottom wall 213 connected to one end of the second annular side wall 212. The second annular side wall 212 and the second bottom wall 213 surround and form the mounting cavity 211. The fixed member 21 may further include a second top wall connected to the other end of the second annular side wall 212, and the second top wall has a window 215. It is to be noted that the fixed member 21 may not include the second top wall, and the other end of the second annular side wall 212 is an open port and directly forms the window 215. In order to facilitate the mounting of the movable member 22 in the mounting cavity 211, the second top wall may be detachably connected to the second annular side wall 212. Alternatively, in order to facilitate the mounting of the movable member 22 in the mounting cavity 211, the second bottom wall 213 may be detachably connected to the second annular side wall 212. The second bottom wall 213 may be provided with an air intake port. The shape and size of the fixing member 21 are not limited and can be selected as necessary. In order to prevent the fixing member 21 from forming an eddy current in the magnetic field environment and generating heat, the material of the fixing member 21 is a non-metallic material, for example, plastic. In one embodiment, the fixing member 21 is a cylindrical plastic bucket. A fixing portion 214 is provided on a surface of the second bottom wall 213 adjacent to the second annular side wall 212, and the fixing portion 214 is used to fix the heat generating member 23, thereby keeping the heat generating member 23 upright. The fixing portion 214 may be a groove or a bump, and the groove receives one end of the heat generating member 23 and engages with it, and the bump is inserted into the groove at one end of the heat generating member 23 and engages with it.

[0040] The heat generating member 23 includes an insertion portion 231 and a blocking portion 232, and the blocking portion 232 is fixedly connected to one end of the insertion portion 231. One end of the insertion portion 231 remote from the blocking portion 232 functions as a first end 233 of the heat generating member 23. An end of the blocking portion 232 remote from the insertion portion 231 functions as a second end 234 of the heat generating member 23, or the blocking portion 232 directly functions as the second end 234 of the heat generating member 23. The first end 233 of the heat generating member 23 is a tip, which makes it easy to insert the insertion portion 231 into the aerosol generating assembly 4. In addition, the second end 234 of the heat generating member 23 is detachably installed on the second bottom wall 213 of the mounting cavity 211, and the first end 233 of the heat generating member 23 is used to be inserted into the aerosol generating assembly 4. The heat generating member 23 is used to generate heat in a magnetic field and heat the aerosol generating assembly 4 to generate aerosol to be inhaled by a user. Also, the dimension of the cross section of the insertion portion 231 is smaller than the dimension of the cross section of the blocking portion 232. The material of the heat generating member 23 is a metal material. For example, the material of the heat generating member 23 may be copper, aluminum, or an alloy. The heat generating member 23 may be a metal column or a metal sheet. Specifically, the heat generating member 23 may be a T-shaped structure, an L-shaped structure, or a tapered structure, and the blocking portion 232 may be formed at the second end 234. In one embodiment, the heat generating member 23 is a strip-shaped metal sheet, one end of the strip-shaped metal sheet forms a tip of an inverted triangle, and the side of the other end has a flange to form the blocking portion 232.

[0041] In one embodiment, the inner surface of the second bottom wall 213 has an accommodating groove 2142, which functions as the fixing portion 214. The accommodating groove 2142 is used to accommodate and fix the blocking portion 232 of the heat generating member 23. The accommodating groove 2142 may be formed by providing a recess on the inner surface of the second bottom wall 213, or may be formed by providing the accommodating groove 2142 on the inner surface of the second bottom wall 213. In another preferred embodiment, the surface of the second bottom wall 213 adjacent to the second annular side wall 212 has an annular protrusion 2141, which is surrounded to form the accommodating groove 2142, which functions as the fixing portion 214, and which is used to accommodate and fix the blocking portion 232 of the heat generating member 23. In addition, the shape and size of the groove / receiving groove 2142 are adapted to the shape and size of the blocking portion 232, so as to easily accommodate and fix the blocking portion 232, thereby holding the plugging portion 231 of the heat generating member 23 in an upright position, and facilitating insertion of the plugging portion 231 into the aerosol generating assembly 4. In one embodiment, specifically, as shown in FIG. 6, a positioning groove 2144 is provided on the surface of the heat generating member 23 where the blocking portion 232 is separated from the plugging portion 231, and a positioning post 2143 is provided on the surface where the second bottom wall 213 is connected to the second annular side wall 212, and the positioning post 2143 functions as the fixing portion 214. In addition, the shape of the positioning post 2143 is adapted to the shape of the positioning groove 2144, so that when the heat generating member 23 contacts the second bottom wall 213, the positioning post 2143 is inserted into the positioning groove 2144, thereby realizing a detachable connection between the heat generating member 23 and the second bottom wall 213, and thereby the plugging portion 231 can be kept in an upright position.

[0042] In one embodiment, the blocking portion 232 of the heat generating member 23 or the entire heat generating member 23 adopts an iron material, or one end of the blocking portion 232 of the heat generating member 23 is provided with a magnetic material. Correspondingly, the portion of the second bottom wall 213 corresponding to the fixing portion 214 is further provided with a magnetic member 216, which is used to magnetically connect to the heat generating member 23, so that the heat generating member 23 and the bottom wall of the mounting cavity 211 are easily connected by magnetic action. The attractive force between the magnetic member 216 and the heat generating member 23 is smaller than the frictional force between the magnetic member 216 and the heat generating member 23 after the plug portion 231 is inserted into the aerosol generating assembly 4, so that the aerosol generating assembly 4 separates the heat generating member 23 from the second bottom wall 213 by the frictional force. Also, the magnetic member 216 may be provided on the inner surface of the second bottom wall 213, for example, on the bottom surface of the receiving groove 2142, or on the outer surface of the second bottom wall 213, or in a groove on the outer surface of the second bottom wall 213. The magnetic member 216 can be fitted into the second bottom wall 213 and fixes the heat generating member 23 by magnetic attraction. The magnetic member 216 may be a magnet. In another embodiment, a magnet is provided at one end of the blocking portion 232 of the heat generating member 23, and the magnetic member 216 may be iron.

[0043] 5, the movable member 22 is accommodated in the mounting cavity 211, and the movable member 22 is slidably connected to the fixed member 21. Specifically, the movable member 22 can slide along the direction in which the aerosol generating assembly 4 is inserted into or removed from the mounting cavity 211. The movable member 22 has a through hole 225, which is used to allow the first end 233 of the heat generating member 23 to penetrate and be inserted into the aerosol generating assembly 4. Preferably, the through hole 225 allows the first end 233 of the heat generating member 23 to penetrate and restricts the second end 234 of the heat generating member 23 to penetrate, thereby separating the aerosol generating assembly 4 from the heat generating member 23 during the process of removing the aerosol generating assembly 4. If the through-hole 225 cannot separate the aerosol-generating assembly 4 and the heat-generating member 23, the heat-generating member 23 must be removed and manually replaced and attached to the second bottom wall 213 every time the aerosol-generating assembly 4 is replaced, which is inconvenient to use. Specifically, the inner diameter of the through-hole 225 is larger than the cross-sectional dimension of the insertion portion 231, and the inner diameter of the through-hole 225 is smaller than the cross-sectional dimension of the blocking portion 232. The inner diameter of the through-hole 225 is larger than the cross-sectional dimension of the insertion portion 231, so that after the heat-generating member 23 is inserted into the aerosol-generating assembly 4, the heat-generating member 23 and the inner surface of the through-hole 225 are spaced apart from each other, which avoids the heat generated by the heat-generating member 23 from being directly transmitted to the movable member 22, and therefore the heat generated by the heat-generating member 23 is used to heat the aerosol-generating assembly 4 as much as possible. To prevent the movable member 22 from forming eddy currents in the magnetic field environment and generating heat, the material of the movable member 22 is a non-metallic material, such as plastic.

[0044] The fixed member 21 and / or the movable member 22 have a position limiting portion (not shown), which is used to limit the sliding of the movable member 22 between the first position and the second position. The second position is located between the first position and the second bottom wall 213 of the mounting cavity 211. In one embodiment, when the movable member 22 is in the first position and the heat-generating member 23 is in the second position, a part of the heat-generating member 23 is inserted into the through-hole 225. When the movable member 22 is in the second position and the heat-generating member 23 is in the second position, the end surface of the movable member 22 and the blocking portion 232 of the heat-generating member 23 are spaced apart from each other to prevent the heat generated by the heat-generating member 23 from being transferred to the movable member 22, thereby effectively avoiding heat loss. When the movable member 22 is in the first position, a portion of the heat-generating member 23 is inserted into the through hole 225, so that when the aerosol-generating assembly 4 is inserted into the mounting cavity 211 and abuts against the movable member 22, a portion of the heat-generating member 23 is already inserted into the aerosol-generating assembly 4, and the aerosol-generating assembly 4 fixes and limits the position of the heat-generating member 23, thereby preventing the heat-generating member 23 from shifting when the aerosol-generating assembly 4 presses the movable member 22 from the first position to the second position. When the movable member 22 is in the second position, the end face of the movable member 22 and the blocking portion 232 of the heat generating member 23 are spaced apart from each other, so that after the movable member 22 is reset from the second position to the first position, the heat generating member 23 is separated from the second bottom wall 213 and kept inserted into the aerosol generating assembly 4, and the blocking portion 232 of the heat generating member 23 is kept spaced apart from the movable member 22, thereby preventing the heat generated by the heat generating member 23 from being directly transferred to the movable member 22, so that the heat generated by the heat generating member 23 is used as much as possible to heat the aerosol generating assembly 4. In the present invention, after the movable member 22 resets the heat generating member 23 from the second position to the first position, the heat generating member 23 does not contact other solid elements but only contacts the aerosol generating assembly 4, so that the heating efficiency of the heat generating member 23 to the aerosol generating assembly 4 can be improved.

[0045] In one embodiment, a bump is provided on the side wall of the mounting cavity 211, the distance between the bump and the bottom wall of the mounting cavity 211 is higher than the height of the blocking portion 232 of the heat-generating member 23 and lower than the overall height of the heat-generating member 23, the bump and the heat-generating member 23 are spaced apart, and the bump functions as a position limiting portion to limit the movable member 22 to the second position.

[0046] The shape of the movable member 22 is not limited and can be selected as necessary. For example, the movable member 22 may be plate-shaped or tubular. In a specific embodiment, the movable member 22 is a sleeve 221, and the sleeve 221 has an insertion cavity 222 for accommodating the aerosol generation assembly 4. One end of the sleeve 221 has an insertion opening 229, and the aerosol generation assembly 4 is inserted into the insertion cavity 222 through the insertion opening 229. The insertion opening 229 of the sleeve 221 corresponds to the window 215 of the fixed member 21, and when the sleeve 221 is in the first position, the end of the sleeve 221 provided with the insertion opening 229 abuts against the inner surface of the top wall of the mounting cavity 211. Specifically, the central axis of the insertion opening 229 coincides with the central axis of the window 215 of the fixed member 21 and the central axis of the opening in the casing 1. Specifically, the sleeve 221 includes a first annular side wall 223 and a first bottom wall 224 connected to one end of the first annular side wall 223, and a through hole 225 is provided in the first bottom wall 224, and the through hole 225 is disposed on the opposite side of the insertion hole 229. The through hole 225 is also provided at the center of the first bottom wall 224. The first bottom wall 224 is further provided with an air inlet 226, which conveys the outside air to the insertion cavity 222, so that the airflow heats the aerosol generating assembly 4 together with the heat generating member 23 to generate aerosol and convey it to the user's mouth. Specifically, the sleeve 221 is a cylindrical plastic tube, the through hole 225 is provided at the center of the first bottom wall 224, and the multiple air inlets 226 are disposed around the through hole 225.

[0047] In another specific embodiment, the movable member 22 may be a sliding plate. The aerosol generating assembly 4 is inserted into the mounting cavity 211, and the insertion end abuts against the sliding plate, which has a through hole 225 and an intake port 226. Specifically, the through hole 225 and the intake port 226 of the sleeve 221 have the same configuration, position and function, so they will not be described here.

[0048] The elastic member 25 is provided between the fixed member 21 and the movable member 22, and the elastic member 25 is used to provide a restoring force to reset the movable member 22 from the second position of the mounting cavity 211 to the first position. In addition, the elastic member 25 can hold the movable member 22 in the first position and prevent the elastic member 25 from rattling. In this embodiment, the elastic member 25 is a spring 251. The spring 251 is provided in the mounting cavity 211 of the fixed member 21, and one end of the spring 251 abuts against the movable member 22 and the other end abuts against the second bottom wall 213 of the mounting cavity 211. The movable member 22 slides in the mounting cavity 211 by the spring 251, thereby realizing that the movable member 22 is slidably connected to the fixed member 21. In a specific embodiment, an annular bump 228 is provided on an outer surface of the first annular side wall 223 adjacent to the first bottom wall 224, and a mounting groove 227 is formed on a surface of the annular bump 228 adjacent to the second bottom wall 213, and an end of the spring 251 away from the second bottom wall 213 of the mounting cavity 211 is fitted onto the first annular side wall 223 and received in the mounting groove 227, thereby preventing displacement of the spring 251 during compression. In another preferred embodiment, an annular groove is provided on the inner wall of the mounting cavity 211, a convex ring is provided on the outer wall of the sleeve 221, the convex ring is accommodated in the annular groove, one end of the spring 251 abuts against a surface adjacent to the first bottom wall 224 of the convex ring and the other end abuts against a surface adjacent to the second bottom wall 213 of the annular groove, and the sleeve 221 slides within the mounting cavity 211 along the direction in which the aerosol generation assembly 4 is inserted or removed by the spring 251, thereby realizing relative sliding between the sleeve 221 and the fixed member 21.

[0049] The spring 251 is made of a non-metallic material, such as rubber, to avoid the spring 251 itself heating up due to the influence of the magnetic field generated by the magnetic field generating member 24, which may affect the elasticity and service life of the spring 251. The spring 251 may have a trumpet-shaped structure to avoid the height of the spring 251 being compressed to the maximum extent from affecting the distance between the movable member 22 and the bottom wall of the mounting cavity 211, and at the same time, the spring 251 itself may be prevented from contacting or colliding during compression. If the spring 251 has a columnar structure, the height of the spring 251 when compressed to the maximum extent may be higher than the height of the blocking portion 232. In this case, it can be understood that the columnar spring 251 functions as a position limiting portion to limit the movable member 22 to the second position.

[0050] In another preferred embodiment, specifically, as shown in FIG. 7, the elastic member 25 includes a first magnetic body 252 and a second magnetic body 253 having the same magnetic properties. The first magnetic body 252 is installed on the bottom surface of the sleeve 221, the second magnetic body 253 is installed on the bottom wall of the mounting cavity 211, and the second magnetic body 253 is installed at a distance from the fixed part 214 installed on the bottom wall of the mounting cavity 211. Since the first magnetic body 252 and the second magnetic body 253 have the same magnetic properties, when the sleeve 221 slides in a direction approaching the bottom wall of the mounting cavity 211, the repulsive force between the first magnetic body 252 of the sleeve 221 and the second magnetic body 253 of the fixed member 21 increases, and a restoring force is generated by the repulsive force between the first magnetic body 252 and the second magnetic body 253, which returns the sleeve 221 from the second position of the mounting cavity 211 to the first position by the restoring force.

[0051] The magnetic field generating member 24 is fitted onto the outer wall surface of the fixed member 21 and electrically connected to the power supply assembly 3. After the magnetic field generating member 24 is energized, it generates a magnetic field to heat the heat generating member 23. The magnetic field generating member 24 includes a coil 241 and a shielding layer 242 fitted onto one side of the coil 241 remote from the fixed member 21. Specifically, the coil 241 is fitted onto the middle position of the fixed member 21. When the movable member 22 is in the first position and the aerosol generating assembly 4 abuts against the movable member 22, the aerosol generating section 42 of the aerosol generating assembly 4 is located within the coil 241, and the insertion section 231 of the heat generating member 23 is inserted into the aerosol generating section 42 and is also located within the coil 241.

[0052] The aerosol generating assembly 4 includes an aerosol generating section 42 and a nozzle section 41. The nozzle section 41 includes a hollow region 412 and a filtering region 411, the filtering region 411 being provided at one end of the hollow region 412, the aerosol generating section 42 being provided at one end of the hollow region 412 remote from the filtering region 411, the aerosol generating section 42 being accommodated in the mounting cavity 211, and at least the end of the filtering region 411 remote from the hollow region 412 being exposed to the outside of the casing 1, so that the user can easily contact the nozzle section 41. The aerosol generated by the aerosol generating section 42 being overheated and atomized is carried to the exhaust passage of the hollow region 412 together with the airflow, and is further filtered through the filtering region 411 before being carried to the user's mouth. In a specific embodiment, the aerosol generating assembly 4 includes a housing tube, one end of which is provided with a filtering material to form a filtering region 411, and the other end of which is provided with an aerosol generating substrate to form an aerosol generating section 42, with a hollow region 412 formed in the middle region. In one embodiment, a first marker 43 and a second marker 44 are provided on the outer wall surface of the aerosol generating assembly 4 at an interval, and the second marker 44 is provided close to the filtering region 411, and the first marker 43 is provided on one side of the second marker 44 away from the filtering region 411. When the first marker 43 is flush with the opening of the casing 1, it indicates that the aerosol generating assembly 4 is in contact with the movable member 22 and that the movable member 22 is in the first position. When the second marker 44 is flush with the opening of the casing 1, it indicates that the movable member 22 is in the second position. In addition, both the first marker 43 and the second marker 44 are marking lines. When the first marker 43 / second marker 44 is flush with the opening of the casing 1, the first marker 43 / second marker 44 is also flush with the outer wall surface of the casing 1. When the end opening of the mounting cavity 211 or the insertion cavity 222 is flush with the opening of the casing 1, it can also be determined by observing that the first marker 43 or the second marker 44 is flush with the end opening of the mounting cavity 211 or the insertion cavity 222.

[0053] Please refer to Fig. 8 to Fig. 10. Fig. 8 is a schematic diagram of the electronic atomization device according to the present invention in a first state. Fig. 9 is a schematic diagram of the electronic atomization device according to the present invention in a second state. Fig. 10 is a schematic diagram of the electronic atomization device according to the present invention in a third state.

[0054] 8, when the aerosol-generating assembly 4 is not inserted, the sleeve 221 is in the first position in the mounting cavity 211, the heat generating member 23 is in the second position, and the spring 251 is in the first compressed state. When the electronic atomizing device 100 needs to be used, the aerosol-generating part 42 in the aerosol-generating assembly 4 needs to be inserted into the insertion cavity 222 through the insertion opening 229 facing the sleeve 221 until the end of the aerosol-generating part 42 remote from the nozzle part 41 abuts against the bottom wall of the insertion cavity 222. At this time, the first marker 43 in the aerosol generating assembly 4 is flush with the opening of the casing 1, the sleeve 221 is still in the first position of the mounting cavity 211, the heat generating member 23 is still in the second position, a part of the insertion portion 231 that penetrates the through hole 225 is inserted into the aerosol generating portion 42, the second end 234 of the heat generating member 23 is fixedly connected to the fixing portion 214 installed on the bottom wall of the mounting cavity 211, and the insertion portion 231 of the heat generating member 23 is installed at a distance from the inner wall surface of the through hole 225.

[0055] By continuing to apply force to the aerosol generating assembly 4, the sleeve 221 slides from the first position in the mounting cavity 211 to the second position in the mounting cavity 211, the aerosol generating assembly 4 is further inserted into the mounting cavity 211, the aerosol generating assembly 4 slides the sleeve 221 in a direction approaching the bottom wall of the mounting cavity 211, the spring 251 is compressed to a second compressed state, and the insertion part 231 of the heat generating member 23 is further inserted into the aerosol generating part 42. At this time, when the second marker 44 on the outer wall surface of the aerosol generating assembly 4 becomes flush with the opening of the casing 1, it indicates that the bottom surface of the sleeve 221 just abuts against the side wall end surface of the receiving groove 2142 provided in the bottom wall of the mounting cavity 211, and the sleeve 221 is in the second position in the mounting cavity 211 as shown in FIG. When the sleeve 221 is in the second position in the mounting cavity 211, the heat-generating member 23 is still in the second position, and the insertion portion 231 is inserted into the aerosol-generating portion 42, the length of the insertion portion 231 inserted into the aerosol-generating portion 42 is equal to the height of the aerosol-generating portion 42, the sleeve 221 is positioned at a distance from the end face of the blocking portion 232 adjacent to the insertion portion 231, and the spring 251 is still in a compressed state.

[0056] When the application of force to the aerosol-generating assembly 4 is stopped, the spring 251 in the second compressed state generates a restoring force, which urges the sleeve 221 to slide in a direction away from the second bottom wall 213 of the mounting cavity 211, causing the sleeve 221 to slide back from the second position of the mounting cavity 211 to the first position of the mounting cavity 211, and at the same time, the sleeve 221 and the aerosol-generating part 42 slide the heat-generating member 23 from the second position to the first position. Specifically, the sleeve 221 slides the aerosol-generating assembly 4 in a direction away from the bottom wall of the mounting cavity 211, and the heat-generating member 23 inserted in the aerosol-generating part 42 is also moved in a direction away from the second bottom wall 213 at the bottom of the mounting cavity 211 following the aerosol-generating assembly 4, thereby separating the blocking part 232 and the fixing part 214 of the heat-generating member 23. When the first marker 43 on the outer wall surface of the aerosol-generating assembly 4 becomes flush with the opening of the casing 1 again, it indicates that the sleeve 221 abuts against the top wall of the mounting cavity 211, i.e., is reset to the first position, and the spring 251 returns to the first compressed state. In this case, as shown in Fig. 10, the heat generating member 23 is in contact only with the aerosol-generating part 42 via the insertion part 231. The heat generating member 23 is not in contact with the fixing member 21 and the sleeve 221. Only the heat generating member 23 is in contact with the aerosol-generating part 42, and the heat generating member 23 is in a suspended state, and all the heat generated by the heat generating member 23 is transported to the aerosol-generating part 42, avoiding heat loss.

[0057] The power supply assembly 3 supplies power to the coil 241 to generate a magnetic field in the coil 241, and the heat generating member 23 generates eddy currents in the magnetic field to generate heat, thereby heating the aerosol generating unit 42 and causing the aerosol generating unit 42 to generate an aerosol. The outside air enters the insertion cavity 222 through the intake port 226, and the generated aerosol is carried along with the airflow to the hollow region 412, and further to the user's mouth through the filtering region 411.

[0058] When the aerosol generating assembly 4 needs to be replaced, a pulling force is applied to move the aerosol generating assembly 4 away from the bottom wall of the mounting cavity 211, and the aerosol generating assembly 4 slides the heat generating member 23 away from the bottom wall of the mounting cavity 211 until the blocking portion 232 comes into contact with the bottom surface of the sleeve 221. A pulling force is then applied to separate the heat generating member 23 and the aerosol generating assembly 4, and the heat generating member 23 falls toward the bottom wall of the mounting cavity 211 due to the action of gravity, and the blocking portion 232 of the heat generating member 23 falls into the fixing portion 214 provided on the bottom wall of the mounting cavity 211 due to the restriction of the through hole 225 and / or the suction action of the magnetic member 216, and the insertion portion 231 of the heat generating member 23 can be kept upright due to the action of the magnetic member 216.

[0059] In the electronic atomizer of this embodiment, the heat generating assembly includes a fixed member, a movable member and a heat generating member, the fixed member has a mounting cavity and is used to accommodate the aerosol generating assembly. The movable member is accommodated in the mounting cavity and slidably connected to the fixed member. The heat generating member is detachably installed on the bottom wall of the mounting cavity and is used to generate heat in a magnetic field to heat the aerosol generating assembly. The aerosol generating assembly in this invention is inserted into the sleeve and drives the movable member from a first position to a second position, and the heat generating member is inserted into the aerosol generating assembly. The movable member is reset from the second position to the first position, the heat generating member is inserted into the aerosol generating assembly and is separated from the bottom wall of the mounting cavity, and the heat generating member and the sleeve are spaced apart, so that more heat generated by the heat generating member is used to heat the aerosol generating assembly, reducing the loss of heat generated by the heat generating member and improving the heat utilization rate.

[0060] The above is merely an embodiment of the present invention, and does not limit the scope of patent protection of the present invention. Any equivalent structure or equivalent process modifications made by utilizing the contents of the specification and drawings of the present invention, or those directly or indirectly applied to other technical fields, are also included in the scope of patent protection of the present invention.
